Patent CA-2335600-A1 (CA)
Inventor: CONSTABLE COLIN
IPC: G06F21/62
Filed: 1999-06-02
Abstract: A Virtual Disk Storage (VDS) system for providing multiple virtual data storage devices (16, 18) for use in a computer system (12) which contains a central processing unit (CPU) (2). The VDS system includes a memory system ( 6) for storing information and a VDS controller (12) which is in communication with the memory system (6) and the CPU (2). The VDS controller (12) partitio ns the memory system (6) into multiple virtual data storage devices (16, 18), a nd then restricts the computer system from communicating with certain of these virtual data storage devices (16, 18). The VDS controller (12) thus selectively isolates at least one of the virtual data storage devices (16) from communicating with the computer system, in order to prevent corruption of information stored in at least one virtual data storage device (16).

Patent CA-2337959-A1 (CA)
Title: Torque converter
Inventor: INOUE KOJI
IPC: F16H41/28
Filed: 2001-02-23
Abstract: A torque converter includes a turbine impeller integrally connected to a pump impeller, a side-cover having a boss and covering the turbine impeller, and a turbine shaft extending through the boss and connected to the turbine impeller. A radial bearing and a one-way clutch are disposed axially adjacent to each other between the boss of the side-cover and the turbine shaft. The radial bearing serves to retain the boss and the turbine shaft concentrically, and the one-way clutch connects the turbine shaft and the side-cover to each other, when a back load is applied to the turbine shaft. Therefore, a load received by a clutch element of the one-way clutch such as a sprag between the turbine shaft and the side-cover is equalized. Thus, when a back load is applied to the turbine shaft, a slipping between the turbine impeller and the pump impeller is prevented, thereby providing a good engine brake effect.

Title: Precipitated calcium carbonate product having improved brightness and method of preparing the same
Inventor: HARRISON JOHN MESCALIN MACGEOG
IPC: D21H17/67
Filed: 2000-07-11
Abstract: A method of significantly improving the brightness and shade properties of a high quality PCC product. The method includes providing a calcium containing feed source that contains discoloring impurities. The calcium containing feed source is formed into an aqueous slurry of calcium carbonate. Thereafter, the slurry is fine screened through a 325 mesh screen in order to yield a slurry of filler grade calcium carbonate. The filler grade calcium carbonate slurry is wet milled in order to liberate the discoloring impurities and reduce the median particle size of the calcium carbonate to less than 2 microns. The diiscoloring impurities are then magnetically separated from the milled calcium carbonate slurry by subjecting the slurry to a high intensity magnetic field. After the magnetic separation step, the purified slurry may be de-watered to yield a dry powder; or alternatively, the slurry may be retained in aqueous form. In any event, the resultant calcium carbonate product has a median particle size of less than 2 microns and a TAPPI  brightness of greater than 96.

Patent CA-2348677-A1 (CA)
Inventor: CARTER JAY W JR
IPC: B64C27/473
Filed: 2001-05-24
Abstract: A rotor for rotary wing aircraft includes a number of features that reduce the collective forces required to control the pitch of the rotor. The spar caps of the spar become joined to one another at the same point where bonding begins between the blade and the spar. The tendency of blade to want to flatten out is minimized since the centrifugal force acting on the spar is located at or near the pitch change axis. Tip weights are located at or near the pitch change axis as well. In a preferred embodiment, the tip weights are located evenly in front of and behind the structural center of the inboard section of the spar. The blade of the rotor and the tip are not swept back.

Filed: 1999-11-16
Abstract: On décrit un système qui permet à un système de gestion des connaissances actives accessible sur Internet de créer un coordinateur d'agent intelligent. L'architecture permet de fournir des informations n'importe quand et n'importe où à un usager qui nécessite ces informations, dans un format approprié en fonction des caractéristiques de l'usager à ce même instant. La personnalisation des informations est également rendue possible du fait qu'on prend en considération l'historique des interactions de l'usager avec diverses applications et des situations du moment en temps réel telles que  'qui est l'usager en ce moment même, où se trouve l'usager en ce moment même, à quel moment l'usager est en session sur le système''. Un sous-système rapide et à échelle variable de priorisation des informations est également utilisé pour incorporer l'opinion du coordinateur d'agent intelligent, les préférences de l'usager, et l'historique des interactions de l'usager. Ce traitement décharge l'agent d'une grande partie du traitement normal ce qui permet aux agents d'être plus sophistiqués et précis sans compromettre la caractéristique de changement d'échelle du système. En outre, la reconnaissance de la parole et la synthèse de la parole combinées à une représentation animée de l'agent intelligent et à des entrées tactiles assurent une interaction efficace, intuitive et émotionnelle avec le système.
